I agree with Chris. Go in November and don't be concerned about hurricane season. January will be the second most expensive time next to the week between Christmas and New Years.
We have been a couple times in November and the weather has been lovely. A couple times we had rain, but it didn't last very long. We like to go in November as it is still the low rate season, but it isn't too hot or humid like the summer.
Congrats on your wedding! You will love CN. It is one of our favorite resorts.
